Helper not started?

[HBDK]

Hi

i have been running this ass in a contianer on my hassio for a couple of weeks now and i have had some crashes.

this is the trace stack from the most recent:

I was wondering if maybe it needs some error handling when calling set_point_temperature?
or if this is something that should be addressed in the libetrv library.

[keton]

I haven't contact with this code for quite a while but it looks like the error is in bluepy not here. etrv2mqtt tries to be thin wrapper around libetrv which is in turn a thin wrapper around bluepy.
If you have an idea how to debug where this error comes from go ahead. My thermostats run just fine with etrv2mqtt as systemd service with auto restart. So maybe this is container related?

i have the same issue. anyone fixed this ?

i got it working. i had to do a reset
